    摘要: The present invention relates to a tracking picture tube of the type in which comb-shaped electrodes or optical detecting means (12, 13) are used for generating a signal related to the position of an electron beam with respect to the strips (5). The tube is characterized in that the deflection unit is arranged to deflect the beams (21r, 21g, 21b) onto selected strips (22r, 22g, 22b) having coincident sides which neighbour finger portions (14, 15) of the same electrode (12, 13), and the selected strips (22r, 22g, 22b), excited by the electron beams, are separated by at least one unexcited strip, respectively.
